As shown in fig. 1, 2 and 3, the delivery device comprises a first pallet 1, a second pallet 2, a controller 3 (not shown), and one or more power units 4.

The first goods shelf 1 and the second goods shelf 2 are opposite in position, the first goods shelf 1 and the second goods shelf 2 are provided with multiple layers of goods channels, each layer of goods channel comprises multiple goods channels, each goods channel is provided with a pushing plate, and multiple goods are placed on each goods channel.

For the target power mechanism 4 of the one or more power mechanisms 4, the target power mechanism 4 includes a first screw 41, a second screw 42, a switching mechanism 43, and a motor 44, the first screw 41 is connected to a push plate on a first lane included in the first rack 1, the second screw 42 is connected to a push plate on a second lane included in the second rack 2, positions of the first lane and the second lane are opposite, the motor 44 and the switching mechanism 43 are electrically connected to the controller 3, respectively, and the motor 44 is also mechanically connected to the switching mechanism 43.

The switching mechanism 43 is used for switching and connecting the motor 44 to the first screw rod 41 or the second screw rod 42, when the motor 44 is connected to the first screw rod 41, the motor 44 is used for driving the first screw rod 41 to rotate in a first rotation direction under the control of the controller 3 so as to push the goods on the first goods way to fall through the push plate on the first goods way, and when the motor 44 is connected to the second screw rod 42, the motor 44 is used for driving the second screw rod 42 to rotate in a second rotation direction under the control of the controller 3 so as to push the goods on the second goods way to fall through the push plate on the second goods way.

It should be noted that, the connection manner between the first screw 41 and the push plate on the first lane included in the first shelf 1 may be: the push plate on the first goods way is provided with a drive screw, and threads on the drive screw are meshed with threads on the first screw rod 41, so that when the first screw rod 41 rotates, the first screw rod 41 drives the drive screw to move, and the drive screw drives the push plate on the first goods way to move, and then the goods on the first goods way are pushed.

Of course, the connection manner of the first screw 41 and the push plate on the first loading lane included in the first rack 1 may also have other connection manners, which are not limited herein.

The connection manner between the second screw rod 42 and the push plate on the second lane included in the second shelf 2 may refer to the connection manner between the first screw rod 41 and the push plate on the first lane included in the first shelf 1, which is not described herein.

In addition, since the motor 44 and the switching mechanism 43 are electrically connected to the controller 3, the controller 3 may control the motor 44 so that the motor 44 can rotate forward or backward, and the controller 3 may send a control instruction to the switching mechanism 43 to control the switching mechanism 43 so that the switching mechanism 43 switches the motor 44 back and forth between the first screw 41 and the second screw 42, and further so that the motor 44 can rotate the first screw 41 and also can drive the second screw 42 to rotate.

In order to facilitate the switching of the motor 44 between the first screw rod 41 and the second screw rod 42, a connecting member may be provided on the motor 44, and the connecting member may have a prismatic shape, and grooves matching with the connecting member may be provided on both the first screw rod 41 and the second screw rod 42. When it is desired to connect the motor 44 to the first screw 41, the switching mechanism 43 embeds the connector on the motor 44 into the groove on the first screw 41. When it is desired to connect the motor 44 to the second screw rod 42, the switching mechanism 43 removes the connector on the motor 44 from the groove on the first screw rod 41, and then inserts the connector on the motor 44 into the groove on the second screw rod 42. After the motor 44 is connected to the second screw rod 42, when it is necessary to connect the motor 44 to the first screw rod 41, the switching mechanism 43 removes the connection piece on the motor 44 from the groove on the second screw rod 42, and then inserts the connection piece of the motor 44 into the groove on the first screw rod 41.

It should be noted that, the controller 3 may be a PLC (Programmable Logic Controller ), and of course, the controller 3 may also be other types of controllers, which are not limited herein.

In addition, to facilitate the switching mechanism 43 to switch the motor 44 between the first screw 41 and the second screw 42, in some embodiments, as shown in fig. 4, the switching mechanism 43 may include a first slide rail 431, a rotating mechanism 432, and a robotic arm 433 (not shown).

The first rail 431 is fixed between the first track and the second track, and the length direction of the first rail 431 is the same as the length direction of the first track or the second track. The rotation mechanism 432 is mounted on the first slide rail 431, the rotation mechanism 432 and the mechanical arm 433 are electrically connected to the controller 3, respectively, the rotation mechanism 432 is also mechanically connected to the motor 44, the mechanical arm 433 is for pushing the rotation mechanism 432 to move along the first slide rail 431 under the control of the controller 3, and the rotation mechanism 432 is for rotating the motor 44 under the control of the controller 3 to connect the motor 44 to the first screw rod 41 or the second screw rod 42.

When the rotation mechanism 432 receives a control command from the controller 3, the rotation mechanism 432 may start rotating the motor 44, and the motor 44 may be connected to the first screw rod 41 or the motor 44 may be connected to the second screw rod 42. That is, in the process of connecting the motor 44 with the first screw rod 41, when the motor 44 needs to be connected with the second screw rod 42, the controller 3 may control the mechanical arm 433 to push the rotation mechanism 432 to move along the first slide rail 431 toward the second screw rod, and when the movement distance reaches the first distance threshold, it may be determined that the connection piece on the motor 44 has been disengaged from the groove on the first screw rod 41. Wherein the first distance threshold is greater than or equal to the depth of the connection member embedded in the groove on the first screw 41. After disconnecting the motor 44 from the first screw 41, the rotating mechanism 432 rotates the motor 44 by 180 degrees under the action of the controller 3, and then the controller 3 can control the mechanical arm 433 to push the rotating mechanism 432 to move along the first sliding rail 431 in the direction of the second screw, so as to embed the connecting piece on the motor 44 into the groove on the second screw 42.

Similarly, in the process of connecting the motor 44 with the second screw 41, when the motor 44 needs to be connected with the first screw 41, the controller 3 may control the mechanical arm 433 to push the rotation mechanism 432 to move along the first slide rail 431 toward the first screw, and when the movement distance reaches the second distance threshold, it may be determined that the connection piece on the motor 44 has been disengaged from the groove on the second screw 42. Wherein the second distance threshold is greater than or equal to the depth of the connection member embedded in the groove on the second screw 42. After disconnecting the motor 44 from the second screw 42, the rotating mechanism 432 rotates the motor 44 by 180 degrees under the action of the controller 3, and then the controller 3 may control the mechanical arm 433 to push the rotating mechanism 432 to move along the first sliding rail 431 in the direction of the first screw, so as to embed the connecting piece on the motor 44 into the groove on the first screw 41.

In addition, in some embodiments, as shown in fig. 4, the target power mechanism 4 may further include a third screw 45 and a fourth screw 46, the third screw 45 being connected to a push plate on a third lane included in the first pallet 1, the fourth screw 46 being connected to a push plate on a fourth lane included in the second pallet 2, the positions of the third lane and the fourth lane being opposite. The switching mechanism 43 may also include a second slide 434 and a third slide 435. The second sliding rail 434 is fixed between the third cargo lane and the fourth cargo lane, and the length direction of the second sliding rail 434 is parallel to the length direction of the third cargo lane or the fourth cargo lane.

The third slide rail 435 is fixed between the first slide rail 431 and the second slide rail 434, the length direction of the third slide rail 435 is perpendicular to the length direction of the first slide rail 431 or the second slide rail 434, and the first slide rail 431, the second slide rail 434 and the third slide rail 435 are located on the same plane, the mechanical arm 433 is further used for pushing the rotating mechanism 432 to move along the third slide rail 435 from the connection position of the first slide rail 431 and the third slide rail 435 to the connection position of the second slide rail 434 and the third slide rail 435, and then move along the second slide rail 434 under the control of the controller 3, and the rotating mechanism 432 is further used for rotating the motor 44 to connect the motor 44 to the third screw 45 or the fourth screw 46.

When the motor 44 is on the first slide rail 431 and the motor 44 needs to be connected to the third screw 45 or the fourth screw 46, the controller 3 may control the mechanical arm 433 to push the rotation mechanism 432 to move along the first slide rail 431 and move the rotation mechanism 432 to a position where the first slide rail 431 is connected to the third slide rail 435, the controller 3 may control the mechanical arm 433 to push the rotation mechanism 432 to move along the third slide rail 435, and when the rotation mechanism 432 moves to a position where the third slide rail 435 is connected to the second slide rail 434, the controller 3 may control the mechanical arm 433 to push the rotation mechanism 432 to move along the second slide rail 434, that is, may cause the rotation mechanism 432 to move from the first slide rail 431 to the second slide rail 434. The rotation mechanism 432 can then be moved along the second slide rail 434 so that the motor 44 can be connected to the third screw 45 as well as to the fourth screw 46.

It should be noted that, in the embodiment of the present application, when the motor 44 is connected to the first screw rod 41, the position of the motor 44 may be determined in advance, and when the motor 44 is connected to the second screw rod 42, the position of the motor 44 may also be determined in advance, and thus, when it is necessary to connect the motor 44 to the third screw rod 45 or the fourth screw rod 46, it may be determined which position the motor 44 is currently located, thereby determining the distance between this position and the connection positions of the first slide rail 431 and the third slide rail 435, and thus, it may be controlled that the mechanical arm 433 pushes the rotation mechanism 432 by these distances to reach the connection position of the first slide rail 431 and the third slide rail 435. The length of the third slide rail 435 may be determined in advance, so when the rotating mechanism 432 reaches the connection position of the first slide rail 431 and the third slide rail 435, the controller 3 may control the mechanical arm 433 to push the rotating mechanism 432 to the connection position of the second slide rail 434 and the third slide rail 435. Thereafter, the position of the rotating mechanism 432 may be pushed with reference to the processing manner of the first slide rail 431 to move the position of the motor 44 on the second slide rail 432.

It should be noted that, when the motor 44 is provided with a connecting piece, grooves matching the connecting piece may be provided on both the third screw rod 45 and the fourth screw rod 46, and the implementation manner of connecting the motor 44 with the third screw rod 45 or the fourth screw rod 46 may refer to the implementation manner of connecting the motor 44 with the first screw rod 41 or the second screw rod 42, which is not described in detail in the embodiments of the present application.

In addition, the connection manner of the third screw rod 45 and the push plate on the third lane included in the first shelf 1, and the connection manner of the fourth screw rod 46 and the push plate on the fourth lane included in the second shelf 2 may refer to the connection manner of the first screw rod 41 and the push plate on the first lane included in the first shelf 1, and will not be described herein.

In addition, when the switching mechanism 43 includes the second slide rail 434 and the third slide rail 435, at this time, the switching mechanism 43 actually includes the first slide rail 431, the second slide rail 434 and the third slide rail 435, the rotating mechanism 432 can move on the first slide rail 431 so that the motor 44 can be connected to the first screw rod 41 and also to the second screw rod 42, and then when the motor 44 is required to be connected to the third screw rod 45 or the fourth screw rod 46, the rotating mechanism 432 can move along the third slide rail 435 onto the second slide rail 434 so that the rotating mechanism 432 can move on the second slide rail 434 so that the motor 44 can be connected to the third screw rod 45 and also to the fourth screw rod 46. That is, when the shipment device provided by the embodiment of the present application is used, the rotation of the screw rods in at least two different lanes in the first shelf 1 can be controlled by one motor 44, and the rotation of the screw rods in at least two different lanes in the second shelf can also be controlled, so that the purpose of saving the motor 44 can be achieved.

In the embodiment of the present application, it is possible that the motor 44 does not rotate any screw at a certain time, and at this time, the motor 44 may be pushed to the initial position, so that the motor 44 may control the movement of different screws at different times again from the initial position. As shown in fig. 5, the target power mechanism may further include a spring 47 and a connection plate 48. The connecting plate 48 is fixed at one end of the third sliding rail 435, the first end of the spring 47 is connected with the connecting plate 48, the second end of the spring 47 is connected with the motor 44, and the motor 44 can return to the initial position under the action of the spring 47 under the condition that the mechanical arm 433 is not pushed.

When the target power mechanism includes the spring 47 and the connection plate 48, after the motor 44 is moved away from the initial position, i.e., the motor 44 moves along the third slide rail 435, so that the motor 44 can be connected with the third screw 45 or the fourth screw 46. When the motor 44 is required to return to the initial position and be connected to the first screw 41 or the second screw 42, since the connection plate 48 is fixed at one end of the third slide 435, the position of the connection plate 48 is not changed, and thus, after the motor 44 is connected to the connection plate 48 through the spring 47, the motor 44 can return to the initial position along the third slide 435 under the action of the spring 47. The initial position of the motor 44 refers to a position corresponding to the spring 47 in a natural state when the spring 47 is not stretched or compressed.

In addition, in the process that the push plate moves along the corresponding goods path under the action of the motor 44, the push plate may incline in the corresponding goods path or the movement is unstable, so that the push plate is affected to push goods in the corresponding goods path. To prevent this and to facilitate movement of the pusher plate in the corresponding lane, in some embodiments, as shown in fig. 6, a ramp 101 is provided on each lane, with the pusher plate on each lane being mounted on the ramp 101 within the lane and being able to move on the ramp 101.

Since the slide ways 101 are provided on each lane, and the push plate corresponding to each lane is mounted on each slide way 101, when the push plate corresponding to each lane moves under the action of the motor 44, the push plate moves along the slide ways 101, so that the push plate can move smoothly during the movement, and the push plate does not incline.

In addition, since the heights of the plurality of pallets in the racks are different, and when the goods in the racks need to be transported, the height of the transport vehicle for transporting the goods is determined to be constant, in order to facilitate the transportation of the goods in the racks onto the transport vehicle, in some embodiments, as shown in fig. 7, the delivery device further includes a first lifting mechanism 5, the first lifting mechanism 5 is located at a side of the first rack 1 away from the second rack 2, the first lifting mechanism 5 is electrically connected with the controller 3, and the first lifting mechanism 5 is used to lift to the positions of the goods lanes of different heights of the first rack 1 to collect the goods falling on the goods lanes of different heights.

After the shipment device includes the first elevating mechanism 5, for the goods in a plurality of goods lanes on the pallets of different heights, can make the first elevating mechanism 5 reach different heights through adjusting the first elevating mechanism 5, thereby make the goods on each of a plurality of pallets in the goods shelves all can transport to the first elevating mechanism 5, through adjusting the height of the first elevating mechanism 5 again, make the height of the first elevating mechanism 5 reach the height of the transport vechicle, thereby be convenient for transport the goods on the pallet of different heights to the transport vechicle.

In some embodiments, as shown in fig. 7, the first lift mechanism 5 includes two rails 51, a lift actuator 52, and a cargo receiving slot 53. The lifting transmission device 52 and at least two guide rails 51 are both fixed on the first goods shelf 1, the goods receiving groove 53 is installed between the two guide rails 51 and is mechanically connected with the lifting transmission device 52, the lifting transmission device 52 is electrically connected with the controller 3, and the lifting transmission device 52 is used for driving the goods receiving groove 53 to move along the two guide rails 51 so as to collect goods falling on goods channels with different heights of the first goods shelf 1.

When the first elevating mechanism 5 includes the two guide rails 51, the elevating gear 52 and the cargo receiving groove 53, since the cargo receiving groove 53 is installed between the two guide rails 51, the cargo receiving groove 53 is not shifted in position in the process of moving along the two guide rails 51 by the elevating gear, so that the cargo receiving groove 53 can smoothly receive the cargo on the pallets of different heights on the shelf.

The manner in which the lifting gear 52 moves the cargo receiving slot 53 is different depending on the lifting gear 52. In some embodiments, the lift actuator 52 includes a drive motor and a rotating shaft, the drive motor is fixed to the shelf, and the drive motor is coupled to the rotating shaft such that the drive motor rotates the rotating shaft. The first end of the rotating shaft is connected to the first end of the cargo receiving groove 53 through a first timing belt, and the second end of the rotating shaft is connected to the second end of the cargo receiving groove 53 through a second timing belt. The rotation shaft is driven to rotate by the operation of the driving motor, and the rotation shaft drives the goods receiving slot 53 to move by the first synchronous belt and the second synchronous belt.

In other embodiments, the lifting drive 52 is a robotic arm. The mechanical arm can now push the cargo receiving slot 53 on both rails 51 and, when the cargo receiving slot 53 is moved to the level of the cargo way, the mechanical arm abuts the cargo receiving slot 53 to prevent the cargo receiving slot 53 from moving along both rails 51.

In addition, since the delivery device includes two racks, in some embodiments, the delivery device further includes a second lifting mechanism 6 (not shown in the drawings), the second lifting mechanism 6 is located on a side of the second rack 2 away from the first rack 1, the second lifting mechanism 6 is electrically connected to the controller 3, and the second lifting mechanism 6 is used to lift to the positions of the racks of different heights of the second rack 2 to collect the goods falling on the racks of different heights.

When the delivery device comprises the second lifting mechanism 6, the second lifting mechanism 6 can receive the goods on the goods lanes with different heights on the second goods shelf, so that the goods in the goods lanes with different heights in the second goods shelf 2 can be transmitted into the second lifting mechanism 6 and cannot fall on the ground.

The second elevating mechanism 6 and the first elevating mechanism 5 may have the same structure.

It should be noted that embodiments of the present application may include one or more power mechanisms, which may or may not be identical in structure. That is, the structure of the other power mechanism than the target power mechanism of the one or more power mechanisms may be the same as or different from the structure of the target power mechanism, which is not limited by the embodiment of the present application.

In summary, the present application is not limited to the preferred embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
